What Makes a Coin Valuable
Mintage, survival, grade, demand, metal. Age is not on the list.

People ask what a coin is worth. The more useful question is what makes any coin worth anything, because the answer is short and it dissolves most of the mystery. Five factors decide the price of a coin: mintage, survival, grade, demand, and metal. Age is not one of them.
1. Mintage
How many were struck. This is the number everyone reaches for first, and it is the least reliable of the five. The United States Mint publishes historical production figures, so mintage is knowable, which is exactly why it gets over-weighted.
2. Survival
How many still exist, which is a different question entirely, and usually unknowable with precision.
Two examples make the point. The 1931-S Buffalo nickel was struck in a quantity of only 194,000 early in the year, one of the lowest figures in the series. Word got out, speculators hoarded them, and the coin is not particularly rare today. Meanwhile the Pittman Act of 1918 authorised melting up to 350 million silver dollars, and the country eventually melted 270,232,722 of them. Whole date-and-mint combinations of Morgan dollars went into the furnace, regardless of how many had been struck.
Mintage tells you how many were made. Survival tells you how many you can buy. Only the second sets a price.
3. Grade
Condition is the factor with the steepest curve. The difference in price between a coin graded MS-63 and the same coin graded MS-65 can be a multiple, not a percentage, and the visual difference between them is slight enough that two experienced graders may disagree. This is why the grading scale matters so much, and why third-party grading exists at all.
It is also why cleaning is catastrophic. A cleaned coin is capped at a details grade, which removes it from the market that pays the multiple. See how to clean coins.
4. Demand
A coin nobody collects is cheap no matter how few survive. Series with large, active collector bases, Lincoln cents, Morgan dollars, Buffalo nickels, support strong prices for their scarce dates because thousands of people are trying to complete a set. An obscure foreign issue of genuinely lower survival may be worth less, because almost nobody is looking for it.
Demand also explains why key dates command premiums out of proportion to their scarcity: everyone building the set needs that one coin.
5. Metal
The floor. A coin cannot be worth much less than the metal in it, because somebody will melt it. A Morgan dollar contains 24.06 grams of fine silver, about 0.7734 troy ounces, and that figure sets a hard minimum which moves with the silver market every day.
For common-date silver and for modern bullion, metal is nearly the whole story. For a scarce date in high grade, the metal is a rounding error.
Why age is not on the list
A worn common-date cent from the 1890s can be worth very little, because tens of millions were struck and a great many survive in worn condition. A cent from within living memory, of the right variety and grade, can be worth thousands. Age correlates loosely with survival and not at all with demand. Nobody in the trade prices a coin by its birthday.
How to actually find a number
Identify the coin first: type, date, mint mark. Then estimate the grade honestly, which means assuming the worse of the two grades you are torn between. Then look up what coins of that exact date, mint mark and grade have actually sold for at auction recently. Realized prices beat published guides, because a guide reports what a dealer might ask and an auction reports what somebody paid.
We publish no prices ourselves. Coin values move with the metals market, the auction calendar and collector fashion, and a number printed here today would be wrong within weeks. A wrong number is worse than none: it invites you to sell too cheap or buy too dear. The resources page points to the guides and auction records the trade actually uses.
Frequently asked questions
What makes a coin valuable?
Five things: how many were struck, how many survive, what condition yours is in, how many collectors want one, and what metal it contains. Age is not among them. A worn 1890 cent can be worth cents while a 1969 cent of the right variety is worth a great deal.
Are old coins always worth money?
No. Age and value are only loosely related. Enormous numbers of nineteenth-century coins survive, and a common date in worn condition may be worth little more than its metal. Meanwhile some coins struck within living memory are scarce and sought after.
Does a low mintage make a coin valuable?
Not by itself. Mintage tells you how many were made, not how many survive. The 1931-S Buffalo nickel had a tiny mintage of about 194,000 early in the year, but large quantities were saved by speculators, so the coin is not particularly rare today. Survival matters more than mintage.
How do I find out what my coin is worth?
Identify the date, mint mark and type first, then look up realized auction prices for that exact date, mint mark and grade. A printed guide gives a retail benchmark. We publish no prices, because coin values move constantly and a stale number misleads.
